PowerBI Interview Playbook

Unpopular opinion: Most Power BI "experts" with 10+ years of experience would fail a senior-level Power BI interview today.

Not because they're bad at their jobs.

Because interviews test what you've forgotten, not what you do daily.

You've been writing DAX for years, but can you explain context transition on a whiteboard?

You've built 50 datasets, but can you articulate why bi-directional filtering is dangerous?

You've refreshed models a thousand times, but can you name 5 Power Query steps that break query folding?

You know Power BI. But do you know how it connects to Synapse, Fabric, Purview, and Entra ID in an enterprise architecture?

I wrote The Power BI Interview Playbook to close this gap.

50 questions. Real code. Real architecture. Real outcomes.

Covering:

→ Data Modelling

→ DAX deep dives

→ Power Query / M

→ Governance & Deployment

→ Cloud Architecture (Azure, Synapse, Fabric)

→ Enterprise Strategy & Migration

Two tracks:

▸ 7–11 years: Technical execution mastery

▸ 11+ years: Architecture and strategy leadership
